-CHARLES A. BARWISE, OF BROQKLYN, NEW XORK.

. COFFEEAND TEA URN'.

To all whom it mja/y concern:

Be it known that I, CHARLES BARWisn, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State' of New York, useful Improvements in Co'fi'ee and Tea Urns,

of which the following is a specification, such as will enable those skilled in the art to which it appertaiiis to make and use the same.

This invention relates to coHee and tea urns and particularly to devices of this class used iii cafs, restaurants, .hotels and like places; and the object of the invention is to provide an improved wherebyahe perfect extraction of the liquid infusion of coii'ee or tea is accomplished and the sai-d infusion rendered clear and perfect as a beverage; a further object being to utilize the heat o'l" a water boiler which forms a part oi the device to maintain the liquid coffee or tea at the desiredtemperature; a Jr'urther object being to provide a coffee or tea urn the operation of which is made contiiiuons by anarrangenient of' two or more liquid coffee containing jars or vessels in connection with a-single boiler, so that while one jar or vessel is being depleted the other or others are being replenished so that said jars or vessels can be used alternately-without experiencing any temporary failure in the supply 0l coffee or tea; a further object'being todispense with the cloth bag usually employed in connection with apparatus of' this classand in which the' coifee or tea to ble-infused is placed, together with other details of such apparatus made necessary by the use of said and the objections to which are well known; andwith these and other objects in scribed and claims.

The invention' is fully disclosed in the following specification, panying drawing-formsa .pai-t, in which the separate parts 4of my improvement are desigL as pointedfout in the appended nated b suitable reference characters .in-V y isplaced, and each' of which each of t Figure 1 isa sectional or tea urn made according to and in which two coffee jars e views, .andi-n which;l j.

device of this classi vview the invention consists in a device of the e class specified constructed as hereinafter de"- of.. which the accom 'flange dand the flanges Patented Dec. 17, 1907.

side view of one of the coee jars or vessels detached or removed from the urn; Fig. 4 a view similar to Fig. 2 but showing a single l form of device or a device involving but one have invented certain new and coffee or tea jar or vessel; and, Fig. 5 a sectional'side vie'w of a coupling device shown at the top of Fig-1. l j

In the practiceI of'iny invention, as shown in Figs. 1 to 3 inclusive, I'provide a boiler (L, which is capable 'of withstanding considerablepressure and wliicttjrnay be heated bv a steam coil7 gas, electricity or 'inaiiy ot er Way, but, inthe lform of construction shown, is heated by an ordinary gas burner a2 which is placed thereunder. The upper front portionof the boiler isvcut away or provided with a recess c3 which extends to the top thereof and from one side to the other, and to a predetermined distance roni'the. bottoni thereof and iii which, in practice, are placed the liquid coHee jars or vessels b, two of which are shown. Y

The boiler av and the liquid coll'ee jars or vessels b when connected are rectangular in cross section and all of said parts areinclosedv by a main outel casing c 'which preferably extends slightly rbelow the boiler and also slightly above thesaine and, in the forni oi 'constructioir shown, vthe liquid coii'ee containing jars 01j )vessels b also extend above the top of the boiler 'and'parallel withy the top of the casing c, `and,between said casing and the boiler, and between the jars or vessels b,

and between the'rOntsQthe jars or vessels and the front fthe oasin'g'fc'are air spaces c2.

and between said ars or've'ssels and the boiler VIn the top of ea` li of the liquid coffee jars I orvessels .b is'placed what'I i call a digester d in which 1the grouliid coffee or other'niaterial consist of a suitevessel or ,receiver yprovided at the t'op with ahatridled and nea'i'5the 'top\.witli a Suspense. coilee or. teaj jars or vessels i gesters are: pi'eferablyof r'less d digesters on -the to is of the liquid dimensions in dfof .the digestefrs dics and said di- V- trans've'rse.section than the said jars or vesmay be broken and the digesters d may thus sels b, and the digesters d and the flanges d3 thereof serve as covers for closing the tops of. the jars or vessels b and lieep the steamand aroma from escapingfroin the said-jarsvessels.

The air spaces c2 prevent the boiler from overheating the coffee or tea in the jars or vessels b which are kept at a proper temperature by a current of het air from the burner a`l passing upward through said air spaces and thev heat from the boiler a also aids in re taining thecontents f the jars or vessels l) at a proper temperature.

The digesters d are provided at a predetermined distance below the top thereof with finely perforated partition plates d* above which are chambers d into 'which hot water .from the boiler is discharged, as hereinafter described.' and below the partitions d4 are chambers d in which the coffee or other inaterial is placed and the bottoms of the chambers d consist of-perforated plates e and e2 between which isA laced a fabric screen e, and the sides of tfie digesters areprovided with inwardly directed stops or fianges dl, and the bottom perforated plate e is provided with strong springs e4 which are pivoted thereto and the ends of which are adapted to pass through slots da in the opposite sides of the digesters, and by means of this construction," by turning the springs e4 the bottoms of the chambers d may be taken out 'whenever desired and the perforated plates e and e2 cleaned and the fabric screen. may also be cleaned or a newjone substitutedffor the old one whenever desired. It will valso be understood that in placing the ground( coffee er other material in'the chambers d of the digesters d, the bottoms of the chambers d 'are taken out and the digesters inverted and said chambers d are filled through the bottoms of the digesters. y

In the form `of constructionshown,4 the n v entend downwardly thereinto nearly to the '.,1jbottoni thereof and which also extend out .through -the top thereof, and these tubes f communicatewith elbowl tubes g which comand Aare 'threade as shown at g2, a detail of this'Econstruetio'n being shown in Fig. 5, andi, 6 0.

thei'saiddigesters 'are provided with threaded v `'nozzles glgarrd mount'edon the threaded ends g2 of' the tiib'e's gare interiorly threaded coupling sleeves g4 providedwith handles g5,

and by turning the coupling sleeves g4 in one direction the connection with the., nozzles g boiler a is provided with twotubes f which portion of the digesters d` municate witlilthev top portion of the boiler a "or other material in the chamb iineans of a pipe h2 to' into yWhen `the gage/spi indicate. that sufficient ,erationl'the digesterv should lie;- Jcleaned and new inaterialzplaced ally produced, bu

be removed or'placed in positionvv 'whenever desired, it being understood that by turning the coupling -sleeves d4 in the opposite direcor j tion the nozzles gi and tubes g may be coui l pled together. l The tubes f are provided with valve casings f2 having valves operated by 'valve stems f3, and the vertically arranged part of the elb'w tubes g are provided with similar valve casings f4 and valves operated by valve stems f", and when the water in the boiler a is heated, pressure in said boiler will be generated which will force the water through the tubes finto the chambers (I5 of the digestersd and this water the perforated plates or screens d in the top portions of the digestcrsand onto the coffee ers d, and when a suflicient amount of water has thus been discharged in the digcstei's d, tlievalve stems f 3 may be operated te close the valves in the valve casing's f2 and the valves in the valve casingsf4 may be opened by means of the valve stems fi to permit steam from the boiler to enter the digesters. This steam exerts pressure on the water and collec or other material in the digesteis and the water is forced through said material and the infusion `thus formed is driven downwardly through the perforated plates e and ef and fabric screens or filters e3 into the liquid jars or fue sels b. d

The boiler is provided with a pressure gage 7i placed in communication. therewith by valve device may be provided if desired, and

lthe jars or vessels b are also provided with gage tubes fr to-fd'eternnne the height of the liquid therci'nf` in practice, the belief a is sind ,with may preferably to about three-quarters of its capacity.
